This invention relates to cigarette packing machines and comprises anapparatus for rejecting incorrectly filled cigarettes or the like. 7

It is already known, in cigarette packing machines, to provide anelectro-magnetic de- 7 vice for rejecting incorrectly filled packets,

the said device chiefly comprising feeler levers which co-operate withthe cigarettes placed in the packet and which, on one or more cigarettesbeing deficient set in operation an ejecting apparatus which moves thecompletely filled packet away from the operations on the correctlyfilled packets. It has al-' ready been previously proposed to adjust themechanism so finely that it operates also when cigarettes which are tooloosely filled are present in the packet and rejects the packet inquestion. These known devices, however, have the disadvantage that whencigarettes which are too loosely filled are present, not only are thelatter rejected, but the correctly filled cigarettes present in the samepacket are rejected also.

According to the present invention, in or der to obviate thisdisadvantage, the rejection of the incorrectly filled cigarettes iseffected so as to move the cigarettes in question away from theoperations on the correctly filled cigarettes during their forwardmovement to the packing machine. In order to cause the ejectingapparatus to operate when cigarettes containing too little or too muchtobacco pass by the feeler levers acting upon the ejecting apparatus,the arrangement is preferably so contrived that the feelers, which aremounted rotatably and are provided with contacts which come into contactwith stationary contacts during movement in one or both directions,thereby closing in known manner the circult of an electrical a by thegrooved drum glare fined with relay which controls the ejectingapparatus.

In order to include the entire length of the cigarettes, a plurality offeeler levers acting independently of one another are mounted side byside lengthwise of the cigarettes.

A constructional form of the invention is shown by way of example in theaccompanying drawing, in which,

506,812, and in Germany January 23, 1930.

Figure 1 is a side elevation of a feed apparatus for cigarettes andFigure 2 is a corresponding view in another working position of theapparatus.

A Figure 3 is a vertical section through Fig ure 1.

I The cigarettes a which are to be sent to the packing machine are fedin a known man-T ner from a supply container 7) to a revolving drum 6provided with peripheral grooves (Z, and are arranged in the grooves ofthe drum by a revolving roller f. According to the invention, aplurality of feeler levers g are pivotally mounted on a common shaft hon the upper side of the grooved drum e Leaf springs z' bear against thefree ends of the feeler levers g, the lower part of which is arcuate,sothat the feeler levers bear with a certain pressure against theperiphery of the cigarettes a which are moved past beneath them by thegrooved drum 6. On the part of the feeler levers g which lies above theaxle h are mounted two contacts a, 0 adjustable by'screws k and m,respectively, and opposed on both sides by a stationary contact p, grespectively. The stationary con tacts p, q are likewise adjustable byscrews 7 ,5 and are connected together and to one end of the magnetwinding of an electromagnet t by an electric lead 8. The lead 8 isconnected to a source of electric current u. The other end of the magnetwinding t is connected by a lead 41 to the feeler levers g and to thecontact pin a, 0 allocated to the said feeler levers. The electromagnett co-operates with an armature lever w, which controls in any knownmanner a mechanical ejecting apparatus not shown in the drawing. j

The mode of operation of the apparatus is consequently as follows:

If the cigarettes'fed from the supply conthe correct amount of tobacco,the feeler levers g exploring the cigarettes areheld in a position inwhich the contact pins n and 0 are out of contact with the contacts 3?and q,

so that the circuit of the electromagnet t is interrupted. If, however,a cigarette which is filled for example with too little tobacco to thesmaller resistance, one or more feeler levers 9 will be moved into theposition shown in Figure 2, in which the contacts p and n touch oneanother, thus closing the 6 circuit of the electromagnet t. The resultof this is that. the armature lever w is attracted by the 'electromagnett and the ejecting apparatus is set into operation, so that onfurtbeeforward movement, the cigarette in quesl tTon isrejected from thecourse of the correctly filled cigarettes. Conversely, for the case inwhich the cigarette conttv w with the feeler levers 9 contains too muchto acco, a movement of one or more fieeien levels '9- i lace in theother direction so that the oiitai. 0 and q touch one another and thecircuit of the electromagnet t is again closed. e invention is of coursenot limited to the constructional form illustrated and may 8! beusedwith feed devices of any construction. The feeler levers or the like,which. explore the may if desired co-operafte with djn ie'ti anicalrelay instead of with an elecreiay, may serve directly for conll the'ifiecting apparatus. In order t e ejectm apparatus will come into onwhen 516 badly filled cigarette contoo much or too little tobacco on aporan of its lelsn h only, a la'ige nfumlgir 'gf one o levers wil preera y' e ffbuted ovgi' ihe entire length of the c; f erce, al'lfho h incertain cases, tgetgirovifi "of-only one eeler levermaybe cient.
